Calling the 2012 Shelby 1000 Mustang a muscle car on steroids is almost an understatement.

Shelby American is showing off its latest creation, a customized-by-hand Mustang that can possess as much as 1,100 horsepower -- and no, that's not a typo.

The street-legal version will check in at 950, but a racetrack-only version of the car will crack the 1,100 hundred mark, according to Shelby.

Auto legend Carroll Shelby's company has been upping the muscle car arms race for years but has really accelerated the firepower recently, jumping from 650 to 800 for Shelby's latest top-of-the-line creation. The 800-horsepower Shelby GT500 Super Snake was the former horsepower king of the hill with 800 horsepower. The 650 horsepower Shelby GT500 sounds almost tame by comparison.

Arch rival Chevrolet has some catching up to do. Its Camaro ZL1 has "just" 550 horsepower. But like Ford, you can still get more. Longtime performance company SLP (Street Legal Performance) offers a souped up ZL1 convertible that claims to have 750 horsepower. But all that horsepower doesn't come cheap. Car and Driver reports the SLP package ads $80,000 on top of the $38,800 convertible donor car.

As for the Shelby, we haven't seen pricing announced yet. But if you have to ask, there's always the V6 Mustang that bases for about $22,000.
